The Partial Hydrolysis of Methyltriethoxysilane

Peroxide‐Grafted PDMS: Hydrosilylation Reaction and Thiol‐Ene Chemistry as an Alternative Pathway

“…These remaining alkoxy groups indicated that the polycondensation was chiefly limited by the reactivity of the alkoxy groups and could explain the low degree of polycondensation obtained even with DM3PSi. Actually, it was previously observed that the reactivity of the alkoxy groups varies with the number of alkoxy group linked to the silicon atom, [9][10][11] as depicted in Equation (5). The third alkoxy group can be considered as a ''dead'' (1) peroxide-grafted silane monomer DM3PSi (2) DMS-S15 (3) condensation of peroxide-grafted silane monomer BP3DM2Si with DMS-S15 (4) condensation of silane monomer DM3PSi with DMS-S15.…”

Preparation and characterization of 3-aminopropyltriethoxysilane grafted montmorillonite and acid-activated montmorillonite

“…This leads to condensation between silane and clay surface hydroxyl groups, and polymerization among silane molecules. In the case of polymerization, different polymers with various sizes can be formed, such as linear, monocyclic, polycyclic and 'cagelike' [21,22] . Only the polymers with suitable size can be intercalated into the clay interlayer space.…”

Preparation and properties of polysilsesquioxanes: Polysilsesquioxanes and flexible thin films by acid-catalyzed controlled hydrolytic polycondensation of methyl- and vinyltrimethoxysilane

“…[13][14][15] This process was found to result in a simultaneous removal of water and catalyst and subsequent progress of moderate and further polycondensation in the increasing concentrations to provide polysilsesquioxanes with high molecular weight. In this work, two processes were improved, as follows: ethanol was replaced with methanol to avoid the complication of structure analysis resulting from the exchange reaction between the ethoxy and the methoxy group.…”
